 gcloud config list project
 gcloud compute project-info describe --project qwiklabs-gcp-01-fde89cd6fa5b | grep default
   - key: google-compute-default-zone
    value: us-east1-b
  - key: google-compute-default-region
    value: us-east1

task 1:

 gcloud compute instances create nucleus-jumphost --machine-type f1-micro --zone us-east1-b

task 2: 这里的service的名字 必须是nucleus-xxx 坑了一下

  gcloud config set compute/region us-east1
  gcloud container clusters create josie-thomas-cluster  --zone us-east1-b
  gcloud container clusters get-credentials josie-thomas-cluster
  kubectl create deployment nucleus-app --image=gcr.io/google-samples/hello-app:2.0  
  kubectl expose deployment nucleus-app --type=LoadBalancer --port=8080

task 3：我这个instance-template的start-script好像没运行起来。最后进到俩instance里手装的nginx -_-||

cat << EOF > startup.sh
#! /bin/bash
apt-get update

service nginx start
